The QueryContinueDrag event enables the drag source to determine whether the drag-and-drop operation should be canceled.

This event creates an alias for the DragDrop.QueryContinueDrag attached event for this class, so that QueryContinueDrag is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the QueryContinueDrag event are attached to the underlying DragDrop.QueryContinueDrag attached event and receive the same event data instance.
